Product details

Overview

STM3221G-EVAL from STMicroelectronics is an evaluation board built around the STM32F217IGH6 ARM® Cortex®-M3 microcontroller, featuring cryptographic acceleration, 16-Mbit SRAM, 3.2" 240×320 TFT LCD with touch, dual CAN 2.0A/B channels, and IEEE 802.3-compliant Ethernet - designed for full peripheral validation and application prototyping in industrial HMI and connectivity gateways.

For engineers reviewing the STM3221G-EVAL datasheet, STM3221G-EVAL pinout (JTAG/SW debug, USB OTG HS/FS, Ethernet PHY interface), STM3221G-EVAL application (HMI development, secure gateway firmware validation, motor control + communication co-design), or STM3221G-EVAL equivalent (e.g., STM3240G-EVAL, STM32429I-EVAL), this page delivers verified hardware capabilities, supported toolchains (IAR EWARM, Keil MDK-ARM, GCC-based SW4STM32), and real-world supply chain context.

Technical Context

The board implements a complete reference design for the STM32F217IGH6 MCU, integrating high-speed peripherals including USB OTG HS (with Micro-AB connector), dual CAN transceivers on a shared DB9 connector, and RMII Ethernet PHY interface with magnetics. It supports boot from Flash, SRAM, or system memory, enabling flexible firmware update and recovery workflows.

Hardware resources include ST MEMS sensors (accelerometer/gyro), I²C EEPROM (64-Kbit), smartcard readers (ISO/IEC 14443-A/B), stereo audio DAC with headset jack, and motor control connector with PWM and current-sense signal routing - all accessible via standardized expansion headers and debug interfaces.

FAQ

Does STM3221G-EVAL support USB Host and Device modes simultaneously?

Yes - the board implements USB OTG High-Speed and Full-Speed with a Micro-AB connector, enabling dual-role operation. The onboard STM32F217IGH6 MCU handles session request protocol (SRP) and host negotiation, validated in ST's preloaded demonstration software for mass storage and HID device enumeration.

What camera modules are compatible with the STM3221G-EVAL extension connector?

The board provides a dedicated ST camera plug-in connector supporting OV9655 (VGA CMOS) and OV2640 (QVGA) modules. Pinout matches ST's official camera daughterboards (e.g., EVL-CAM-OMNIVISION), with parallel DVP interface, 24 MHz clock, and GPIO-controlled reset and power-down signals.

Is the Ethernet interface fully functional out-of-the-box?

Yes - the board integrates a standard RMII PHY interface with integrated magnetics and RJ45 jack, compliant with IEEE 802.3-2002. Preloaded demo firmware includes LwIP-based TCP/IP stack with DHCP, ping, and web server examples, tested with 10/100 Mbps switches and standard Cat5e cabling.

Can the STM3221G-EVAL be used for cryptographic algorithm validation?

Yes - the STM32F217IGH6 MCU includes hardware AES-128/192/256, SHA-1/SHA-256, and public-key accelerators. ST's demonstration software includes benchmarked crypto routines and key-generation examples, with timing measurements traceable via ST-LINK/V2 SWO output and validated against NIST test vectors.
